SPECIFICATION forming-part of Letters ratent No. 707,240, dated August 19, 1902. y

Application filed November 16,1901,l senti No. 82,550. (No model.)

To all whom t may concern:

Be it known that I, FRED H. KNAPP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois,

Vhave invented new and useful Improvements in Shade Adjustments, of which the following is a specification.

My invention relates particularly to shade adjustments of the general nature of those described in my Patent No. 668,800, February 26, 1901, and that of Clarence W. Blackstone,`v

assigner, No. 674,331, May 14, 1901.

My primary object is' to provide means for controlling themovement of the free end 0f a curtain which is as a whole vertically adj ustable. 2

Myinvention is shown in the preferred form in the accompanying drawings, in which- Figure 1 is a broken elevational view of a window equipped with an adjustable shade to which my present improvements have been applied; Fig. 2, a broken verticall section, taken as indicated at line`,2 of Fig..3 and showing a connection between a lower shade-v corner and a guide-rod; Fig. 3, a transverse section at line 3 of Fig.-2; Fig. 4, a vertical section at line 4ofFig'. 3; Fig. 5, a horizontal section at line 5 of Fig. 4, and Fig. 6 a detached plan view of a combined intermediate guide-rod bracket and slide-stop employed.

A represents a window-frame; B, upper stationary combined guide-rod and pulleybrackets of the kind described in said Patenti No. 668,800; C, guide-rods connected withY said brackets; D,- sliding shade-roller brackets of the kind described in said Patent No. 674,331; E, a shade-roller bearing a shade E; F, cords connected with the brackets D and passing over pulleys a in the brackets' B, said cords uniting in a cord F', connected with a' cord-stop F2, the latter constituting a separate invention, described and claimed in my pending application, Serial No. 84,648, led December 4, 1901; G, intermediate/combined guide-rod brackets and slide-stops, and H connections between the lower corners of the shade and the guide-rods.

The connections H and the arrangement of the slide-stopsG constitute the chief features of novelty of the present application.

A bracket G is clearly shown in Fig. 6, from which it will be understood that the bracket embraces the guide-rod and is securedtothe window-frame, affordinga firm xturer. The lower ends of the guide-rods arev secured to the window-frame in any suitable manner. (Not shown.) y

Each connection H comprises, preferably, a shade-carried slide-supporting rnemberHv and a slide H2, provided with al pivoted tongue H3, freely entering a socket inthe member H and servingas a means for moving saidslide. The shade-carried part-Hfcomprises a sheetmetal clip bent totriangular shape to ftthe lower wooden binding-,strip b of the shade, said clip being firmly secured in place by inwardly-stamped prongs b', engaging the lower edge of the strip h, anda pin or rivet b2, passing .through'the upper portion of said strip. The'prongs b are solocated astoalford beneath them a recess orsocket b2 for the tongue IIE?. The slides H2 comprise short tubes which fit looselyon the guide-rods and arefprovided with pivotal'lugs connected by pins c with the tongues H2, the latter being slotted to receive the lugs. The tubes may be of pressed wood fiber or other material of a suitable nature to avoid objectionable rattling onli-he guide-rods, orfelt washers c', held in place by caps c2, may serve" the same purpose.

-Likewise any suitable expedient may be adopted to prevent the tongues H? from rattling, while not interfering with the requisite freeness of movement within the socketsbs.

The operation will be understood readily. The shade-roll E may be adjusted tolany desired vertical height through the medium of the cord F. Itmay be dropped till the'brackets D encounter the brackets G, in.1which case the shade may be drawn to .cover the lower window, or, assuming the roll to be j ust above the bracket G and the curtaintobe rolled up till the slides H2 engage the brackets G, the roll may be raised to any desired height, in which case the shade will'by'the same action be unwoundto-cover the Iupper window. Thus it will be seen that the brackets G serve in this latter operation tohold the lower end of the shade depressed while the roll is raised, causing the roll to revolve.

Within the limits of their traverse the slides H2 move freely on the guide-rods, and binding is prevented by the relative movability in a plane parallel with the shade of the parts IOO of the connection between said slides and the shade. Objectionable swaying of the lower end of the shade is prevented, and the expedient permits the use of adjustable rolls in proximity to lace curtains without danger of injury to the latter. Moreover, the curtain is guided properly in Winding on its roll, so

that fraying of its edges is prevented. It Will be noted that this feature is of advantage With shades having non-adjustable rolls.

Suitable muftling-Washers (not shown) may be used in connection with the brackets G, if desired to prevent noise when either the slides I-I2 or the sliding brackets D encounter the xed brackets G.

Changes in details of construction within the spirit of my invention may be made. Hence no undue limitation is to be understood from the foregoing detailed description.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a device of the character described, a shade provided at one end with suitable actuating means, vertical guide-rods, and guiding means for the free portion of the shade, comprising slides on said rods, and slide-supporting means on said shade near the free end thereof and engaging said slides, the slide and slide-supporting means of each set being capable of relative movement in a plane parallel with the shade, substantially as described.

2. In a device of the character described, a shade provided at one end with suitableactuating means, vertical guide-rods, and guiding means for the free portion of the shade, comprising slides on said rods, and slide-supporting means on said shade near the free end thereof and engaging said slides, one of said last-named parts of each set bearing a pivoted tongue and the other a recess for receiving said tongue, substantially as described.

3. In a device of the character described, a shade suitably attached at one end, guiderods, and guiding means for the free part of the shade, comprising slide-supporting members connected with said shade, and having suitable recesses, and slides on said guiderods provided with pivoted tongues engaging said recesses, substantially as described.

et. In a device of the character described, a shade provided at one end With suitable actuating means and at the opposite end with a binding member, clips connected With said shade at said binding member and forming sockets beneath said member, guide-rods,and slides on said rods having projections engaging said sockets, substantially as described.

5. In a device of the character described, the combination of vertical guide-rods, rollsupporting slides connected therewith, aroll supported from said slides, and bearing a shade, slides connected with said rods and With the shade near its free end, ixed slidestops intermediate said first-named slides and said second-named slides, and means for actuating said roll-supporting slides, whereby the roll may be raised and the shade drawn at one operation, substantially as and for the purpose set forth.
